Sperm counts decline drastically
Men are producing a lot less sperm. There has been a drastic drop in the number of sperm produced by men in recent years, and it’s getting worse.
Overall, there is a significant worldwide decline of more than 50% in sperm counts in the past 46 years, a decline that has accelerated in recent years. Sperm count declines among men in America and Canada have accelerated in the last five years, and this reflects a crisis related to our modern environment and lifestyle, including diet, with broad implications for the survival of the human species.
Eating a big fat steak may not be so manly after all! A 2017 study found that red and processed meat like steak, bacon, and cold cuts lowers sperm count and mobility. Another study found that high-fat dairy products like whole milk, ice cream, and cheese were associated with lower sperm mobility and abnormal shape.
Researchers, who studied men ages 18 to 20, found that those who followed a vegetarian diet had higher sperm counts — 25.6 million more per ejaculate, to be exact.
Switching to a healthy vegan diet rich in fruit, vegetables, and whole grains while young could help prevent fertility issues later in life. Men on a Western diet had lower levels of the chemical inhibin-B, which may signal damage to sperm-producing Sertoli cells.
